Hoffman Tactical AR-15 Printable Lower

about

Purchase reinforcement parts and support the creator of this lower at hoffmantactical.com! The Hoffman Tactical AR-15 lower is one of the most popular printable AR-15 lowers available at this time. This design has been widely printed and as such is one of the most well-tested designs available. This design is a single-piece print whose most visible feature is a large "rib" rising above the left side of the lower and connecting with the buffer tower, serving as a strong reinforcement for this critical part. As with other printable lower designs, the front takedown pin hole is achieved via two printable pin plates which are bolted on. This lower comes in two versions - the “Basic” version and the “Super” version. The difference between these two versions is the method of reinforcement. The Basic version utilizes common hardware store components for reinforcement, while the Super version utilizes a reinforcement kit available at the designer’s website, hoffmantactical.com.
